I'm unable to reproduce this problem (Debian/bookworm, Gnome Shell), but
I vaguely remember other reports about xdg-open not working in some
circumstances -- I don't remember the details.  Anybody else remember?

Hm...  was it something to do with timing and the weird way that
xdg-open works?  Hm, no, don't remember.
